I have recently (Spring 2026) moved from Windows to Linux. It took me a while to figure out how to speedrun Lotus3 on Linux. I have created a step-by-step guide for it: Here

This guide can be also used for other MSDOS games.

Speedrunning in Linux is considered same with Windows speedruns: MSDOSEMU

Note: There are still unsolved problem about non-english keys on non-english keyboards on this setup. Non-english keys on non-english keyboards is not recognized by DOSBox (running under Wine).
